1n (the drawings,:A- designates a standard Window sash o'f'the sliding variety, which is equippedwithv an upper; nailB, alower rail C, and stiles-D and-E. F designates av-dividing railwhich eXte-n'ds horizontally of the sash A at a point spaced downwardly from the upper rail G designates the adjustable-closure element or ventilator sash oft-he sash-A, said adju stable closure element G heinghinged ati-ts upper edge to the sash A by hinges H, and being comprised ofan upper rail J a lower'rail K, andstiles L. The upper-rail B,;the sti1es D-and E, and the dividing bar-F ofthesash A are cut away to providea rectangular recess M in which the adjustable closure-elementgisi seatedwhen'same is in aclosed position,-and interposed between said closure element when same s closed positionand the vertical walls of said rectangul arv recess :is a gasket N v of'suitable Weatherstr pping material, which serves to insure-a.weathertight joint between the elements referred. to. v

Theclosure. element Gr :is arrangedatwa rectangular opening P and: is adjustable on j its hinges so that: thesamemay be :movedto position to'control passage of lair-through said opening, and to'prevent passage through I said opening ofwfiies andother insects I preferably employ .-a screen R. Elie screen includes a rectangular frame t S which is seated in a suitable recess adjacent" to the I rectangular opening P, so; that .no portion of the screen extends outwardly beyond thetadjacent outer face of the sash A, and. said frame is removably secured in place in said recess in any suitablemanner.

.Thesash A is, of course,- provided Withthe usual pane, or panes of glass A seoured in place in the ordinary manner andlthe ad- :justable closure element G isv likewise ,pro- 'vided with one or" more panes ofglass' G.

'Referring now to my improved means' for imparting movement to the ad ustable closure element G wlth respect to the sash A, 1 designates an arm pivoted at one of its ends to the stile E in the manner illustrated at the point designated by the reference character 2 in Figs. 3 and 4 of the drawings. This arm 1, at the end remote from the pivotally attached end thereof, is provided with a portion 3 which is arranged. at an angle with respect to the remainder of said arm, and an en closed slot or guideway 4 is formed in said arm which extends from a point close to the outer end of the angularly arranged portion 3 to a point spaced inwardly a slight distance from the pivot at the point 2. The shape of the slot or guideway 4 conforms to that of the arm 1; that is to say, said slot or guideway comprises a portion 1 which extends longitudinally of the main portion of the arm 1, and an angularly arranged portion 3 which is a continuation of the portion 1 and extends longitudinally of the angular portion 3 of said arm 1. At its lower edge and at a point approximately midway of the length thereof the arm 1 is provided with a downwardly extended ear 5, and 6 designates a link which is pivotally attached at one of its ends to the ear 5 and at its opposite end to the closure element G.

Arranged for longitudinal movement within a tubular element 7 arranged in a vertically disposed opening 7 in the stile E (Figs. 3 and 4) is an operating rod 8, said rod being secured at its upper end by a suitable means tov a flat bar 9 which is mounted for vertical movement in a guideway 10. The guideway 10 is secured against side wall of a recess E (Figs. 1 and 2) located adjacent to the recess M, and a pin 11 carried by the flat bar 9 extends outwardly therefrom and projects into and through the slot or guideway 4 formed in the arm 1.

At its lower end the operating rod 8 is provided with a portion 8 which is bent at an aproximate right angle to the main body portion of the rod, and this bent portion is extended outwardly through an elongated opening 12 formed in the stile E of the sash A and through an elongated slot 13 formed in the inner wall of a depressed plate 14, which is secured to the stile E and is seated in a recess 15 formed in said stile E adjacent to the elongated opening 12 (Figs. 3 and 4). Mounted on the bent portion 8 of the operat ing rod 8 at the outer end thereof is an operating element 16, the inner face of said oper ating element being spaced slightly from the outer face of the depressed and slotted inner wall of the plate 14, and a plate 17 being interposed between said operating element and said outer face of said depressed and slotted inner wall of said plate 14. Loosely mounted on the bent portion 8 of the operating rod 8 and arranged in contact with the face of the inner depressed wall of the plate 14 opposite to that with which the plate 17 contacts is a second plate 18. This latter plate is urged toward the depressed inner wall of the plate 14 by a coil spring 19, the opposite ends of which contact respectively with the plate 18 and a pin 20 carried by the operating rod portion i 8. The inner depressed wall of the plate 14 is provided with one or more vertical rows of inwardly projected nubs 21, and the plate 18 is provided with one or more apertures 22. alined vertically with the row or rows of nubs 21. By referring to Fig. 7 it will be noted that the operative element is substantially flush with the adjacent face of the sash A.

In view of the arrangement just described it is plain that when the operating element 16 i grasped and moved vertically to impart like movement to the operating rod 8, the plate 18 will yield because of the presence of the coil spring 19, so that said plate may pass over the nubs 21. It is likewise obvious that as the aperture or apertures 22 in the plate 18 register with the nubs 21 during such movement of the operating rod, the spaced nubs will be successively projected into said apertures. It follows, therefore, that the operating rod 8 may not be accidentally moved vertically to any substantial degree, for if such movement were initiated it would continue only until the aperture or apertures in the plate 13 registered with one or more of the nubs, when such nubs would extend into the aperture or apertures and arrest the movement of the operat ing rod.

Extended longitudinally of the dividing rail F of the sash A is a rock shaft 123, said rock shaft being arranged within a recess 24 formed in said dividing rail and being rotatably maintained in position therein by suitable straps 25 (Figs. 5 and 6). At one end of the rock shaft 23 a bifurcated element 26 is rigidly fixed thereto, and spaced longitudinally of the rock shaft are positioned sealing members 2? which are rigidly fixed to the rock shaft and move therewith. 28 designates a pin which extends outwardly from the flat bar 10 already referred to, said pin being adapted, on downward movement of the bar 10 in response to movement of the operating rod 8, to pass between the spaced legs of the hifurcated element 26 in a manner to engage said legs and impart downward and outward movement to the outer portion of the bifurcated element, whereby rocking motion will be imparted to the rock shaft 23. The closure element G is provided with openings 29 5) into which the nose portions of the sealing members 2'? pass when the closure element is moved to a closed position, the inclined faces 27 of the nose portions of said sealing members contacting with and passing behind the upwardly extended leg of the angle member 30 at the bottom of the closure element, whereby said closure element will be drawn into very close contact with the gasket ar ranged about the opening P in the sash A to seal said sash and thus render same weatherproof. 7 At the, end of thero'ck shaftopposite from the end thereofat which the bifurcated element 26' islocated, I provide a torsional spring 23 which tends to rotate the rock shaft in the direction indicated by the arrow in Fig.5. 7 V

When in the use of my improved ventilating sash it is desiredto move the adjustable closure element from a closed to an open position the operating element 16 will be grasped and moved upwardly. This, of course, will result in the operating rod 8 and lint bar 10 receiving like upwardly movement, and as a result thereof the pin :28 extending from said fiat bar will move the bifurcated element 26 from the position in which it is shown in Fig. 4 to that in which itis shown in Fig. 5. In

consequence of such movement of the bifurcated eleinent,-the rock shaft 23' will be rocked to cause the sealing members 27 to be raised from the position 1n which they are shown in Fig. 6 to that position in which said sealing members are shown in Fig. 5, in which latter position the closure element will be unsealed. Oncontinuationof the upward movement of operating rod 8 the pin 11 will contact with the wall 4F of the slot or guideway 4, and becausesaid pin is guided so that it travels in a true vertical path, the lower portion of the arm 1 will be cammed'outwardly as designated by the arrows in Fig. 1, whereby the closure element G which. is connected to said arm by the link 6w'ill be moved outwardly tothe open position in which same is shown in Fig. 3. a

When the closure element G is in an open position and it is desired to move same to a closedposition', the operating rod 8 will be moved downwardly,- thus causing the pin 11 to move against the face 45 of the slot or guideway in a manner to cam the outer portion of the arm 1 downwardly and inwardly and thus move the closure element to a closed position, The final movement of the pin 11 takes place after the arm 1 reaches the position 111 which 1t is shown in Fl g. 4;, and said final movement comprises passage of the p1n downwardly through the portion 3 of the. slot or passageway l. During such passage of the pin 11 the pin 28' will pass between the legs of the bifurcated element 26, will move said bifurcatedelement downwardly to the position in- Which it is shown in Fig. 4e,

whereby the sealing members will engage and seal the closure element G. H e

From the foregoing it is pl'ainthat during a single operation of the operating element- 16 the closure element G i-s unsealed, unlocked,

' and raised, or lowered, locked, and sealed,

depending on the direction of movement of said operating element, foritis plain that when the pin 11 is locatedinthe portion 3 of the slot or guidewa-y l, the closure element, may not be movedon its hinges to an open the: arm 1 and the adjacent elements asso- 1 eiated therewith areoarranged in the recess E formed in thestile E,- and also. that said closure. element G is provided with a flange G which, when'the closure element is in a closed position, covers the recess E as shown,

in Fig.1; In view of this arrangement, it is plain that when a closed position,

1 and link 6 will befolded together, andwill be positioned within the recess E, so that i said elements are entirely out of the weather,

hence ice and; snow may not accumulate on the arm and link referred to so as to interfere with the ready operation thereof Also,

becausel employ the tubular member 7 within which the: rod 8 operates, clos'e contact may; be obtained between said tubulanmemberand rod, hencepassa'ge of air from the outside of the sash A longitudinally of the rod 8 is prevented. a V r Due to the fact that the outer face of the operating. element 16 is substantially flush with the adjacent face of the sash A, said sash may slide relative to an associated sash without said operating element striking said associated sash;
